i mimi rlizzx'iv f' 'n in 235. these pawls being arranged to contact-l stance in Fig. '2, where the two gates 1f) are shown 1n their raised position. the food of lthe tide being indicated by the letter fr. .\s

shown in said figure, the ears '22 are stopped below the. edge of the caisson openings.

1n Fig. 1 is shown a battery of four caissons and within each caisson is a fioat'QB. each float preferably comprising a steel housing having an aperture 24 closed by means of a cap 25. By means of these apertures 211'. the floats can be filled with water so that they can bevexactly weighted, the caps serving to prevent any egres or ingress of water after the float has been charged.

Secured ne'ar each end of each float are the opstanding raelr bars 2G, these. rack bars extending through suitable openings 27 within the, floor of the pier. asshown in Figs. 1 and These raclt bars '2G are Secured to the flanges '15. fixed to the` top ofthe floats and are held by means'of suitable bolt-s 29. As shown in Fig. 1. the. rack bars are positioned near opposite ends of the floats.

In referring to lFigs. "l and-4. itlwill be noticed that. the outstanding levers 13 of the detents` are locatedfiin the path of the fioats 125. so that as these floats descend, they engage the spring atftuated detents. causing a release. of the fimitactuated gates 1f).

Secured to the. btan'is as' shown in Figs. l and are the bearings 30. and held within these bearings is the drive shaft 31. Held upon the. drive shaftjl are. the rack gears It. these gears being held at one. end against the. faces of the. pawl plates` 33, and at the opposite end against the collars 34. As shown in Fig. the pawl plates-33 are provided with Suitable. pivotpins 34', upon vwhich are held the. spring actuated pan-'ls with thc` rack gears Ifl. The gears 32 are also in mesh with the teeth i of the rack bars iti. as shown in l `ifs. 2 and fi. The pawl disks are lieved to the shaft fl, while the rack gears 3'?. loosely revolve` upon the shaft ill.

in order to normally hold the rack bars 2G in engagement with the goals 3;. I employ the. grooved sheaves 3G. rotating between 'suitable collars 37, held upon a shaft 3S. se'- cured within suitable bearings 3). this construction being clearly shown in Fig. 3.

'.\t one end, as shown in Fig. l, thex shaft 3l is provided with a gear 4t). this gear meshing with the pinion 41 carried upon a shaft 42. this shaft also having secured to it the gear 43. in turn meshingwith the pinion 4t secured to a shaft 45, which shaft in t-urn has secured to it. the gear 46 meshing with the pinion 47 upon a suitable shaft 4S. provided with the drive pulley 49.

Ny tidal motors may be arranged-singly or in batteries.

The operation of my motor is as follows:

cured between suitable piles. the gates 19 are closed. in which position the detents 12 lock over, the shoulders to hold these'gates in c..

locked position. `As shown. especially in Fiel 4. each fate 1t) is' )rovided with an air chainber 20. this chamber being of a buoyant capacity sufiicient to promptly raise thecon# nected gateV when the gate is submerged. y

In the operation of the device the gates would be kept closed nntii the flood of thev tide. The floats would thenvbe released and as they' descended each rack 2G would rotate its connected gear 32, the combined gears rotating the drive shaft 3l. The floats 223 would bc. weighted` preferably 'by water7 and .in Fig. 3 the. float is shown as weighted with water up to the line y. The train of gearing 3. (3 and 47 would be so timed that the, tide would ebb and flow by .ha As the tide recedes, theweighted floats will gradually descend. \s has been stated,

however. the. downward movement of tho floats .'Ziis very much slower than the niovenient of the tide. so tliat. b v the time the ffoats arrive at their lowerinost position` the tide will again have risen to thehigh water mark. As the. tide reeedes. the float carried gates of course descend. and at the. ebb of the tide are locked by means of the de tents 12.

From the foregoing it will be noticed thatthe-floats are periodically actuated and that they in their downward movement operate a shaft.. the. movement imparted to which is stored through any suitable mechanical 'lllt'illlS.

in said caisson, adetent to hold said gute in locked condition, a lient secured to said gate to raise the saine. a stop limiting the nii-- ward movement of said gate, a ioat within said caisson said detent being located within the 'with of said (ioat, e rack har extending' from said float, a shaft rerolnlily :iet-:wed above said float, and a grar 'wheel in nani und ratchet engagement with ,smid shaft and meshing with Said Tach liar, ail arrzinjril substantially as and for the purpose sist forth.
